You know that JRuby is Ruby for the JVM, but what does that really mean? JRuby is compatible with Ruby 4 and runs Rails, but also enables use cases that regular Ruby can only dream of:

• Precompiling code for commercial products
• Single-file deployment with any JDK on any device (even mobile and embedded)
• Low-overhead profiling of production apps
• Simple, powerful multi-threading that uses all cores
• Cross-platform libraries for graphics, GUIs, games and AI

And with JRuby 10.1, we're adding new and amazing features and optimizations every day. You've never seen Ruby like this!

This talk will present several fun and cool JRuby use cases that are difficult or impossible to do with regular Ruby. You'll learn how to do more with Ruby and bring Ruby to more places.
